SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: Guaranty Bancshares, Inc. (“Guaranty”) is a bank holding company headquartered in Mount Pleasant, Texas that provides, through its wholly-owned subsidiary, Guaranty Bank & Trust, N.A. (the “Bank”), a broad array of financial products and services to individuals and corporate customers, primarily in its markets of East Texas, Dallas/Fort Worth, Greater Houston and Central Texas. The terms “the Company,” “we,” “us” and “our” mean Guaranty and its subsidiaries, when appropriate. The Company’s main sources of income are derived from making loans throughout its markets and investing in securities issued by the U.S. Treasury, U.S. government agencies and state and political subdivisions. The Company’s primary lending products are real estate, commercial and consumer loans. Although the Company has a diversified loan portfolio, a substantial portion of its debtors’ abilities to honor contracts is dependent on the economy of the State of Texas and primarily the economies of East Texas, Dallas/Fort Worth, Greater Houston and Central Texas. The Company primarily funds its lending activities with deposit operations. The Company’s primary deposit products are checking accounts, money market accounts and certificates of deposit. Basis of Presentation: The consolidated financial statements in this Quarterly Report on Form 10-Q (this “Report”) include the accounts of Guaranty, the Bank, and their respective other direct and indirect subsidiaries and any other entities in which Guaranty has a controlling interest. The Bank has six wholly-owned non-bank subsidiaries, Guaranty Company, Inc., G B COM, INC., 2800 South Texas Avenue LLC, Pin Oak Realty Holdings, Inc., Pin Oak Energy Holdings, LLC and White Oak Aviation, LLC. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies followed by the Company conform, in all material respects, to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the financial services industry. The consolidated financial statements in this Report have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of the Company’s financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s consolidated financial statements, and notes thereto, for the year ended December 31, 2018, included in Guaranty’s Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. All dollar amounts referenced and discussed in the notes to the consolidated financial statements in this Report are presented in thousands, unless noted otherwise. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions may also affect disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recent Accounting Pronouncements: In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income. This issue came about from the enactment of the Tax Cuts and Jobs Act on December 22, 2017 that changed the Company’s income tax rate from 35% to 21%. The ASU changed current accounting whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The ASU is effective for periods beginning after December 15, 2018 although early adoption was permitted. The Company adopted ASU 2018-02 in the first quarter of 2018 and reclassified its stranded tax effect of $486 within accumulated other comprehensive income to retained earnings at March 31, 2018. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies the accounting for goodwill impairment for all entities by requiring impairment changes to be based on the first step in today’s two-step impairment test, thus eliminating step two from the goodwill impairment test. In addition, the amendment eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step two of the goodwill impairment test. For pubic companies, ASU 2017-04 is effective for fiscal years beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is in the process of evaluating the impact of this pronouncement, which is not expected to have a significant impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which sets forth a "current expected credit loss" ("CECL") model requiring the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. For public companies, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company expects that the transition will cause a material increase in the allowance for expected credit losses upon adoption on January 1, 2020. The Company’s transition team for the adoption of this ASU has evaluated the segmentation of credit pools and is currently studying the impacts of running parallel models for calculating the expected losses using various forecasts and qualitative factor adjustments. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU were effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. We adopted this ASU on January 1, 2019, at which time we recorded a lease liability and a related right of use asset of $12.0 million. These are included in other assets and other liabilities on our consolidated balance sheets as of June 30, 2019, and required disclosures are included in Note 9.
